2. There is a white horizontal line on the nail, which is about 1 ~ 2mm wide. Because the delivery process is a kind of pressure for the baby, about 90% newborns can find this situation under their nails when they are 2 months old. Except the pressure during labor, most of the rest are caused by short-term stop of nail growth due to severe physical discomfort or malnutrition (lack of calcium, protein and vitamin B3). When major diseases occur (such as high fever, severe vomiting, etc.). ), you won't find a horizontal white line on your nails, it will only appear after about one to two months. If the older baby has white lines on his nails, it means that he suffered from a serious illness (such as enterovirus) that requires hospitalization several months ago, and even his nails will break (such as enterovirus 7 1, Zazie virus, etc.) .3? Normal change (the necessary process of baby's nail growth). ? Iron deficiency anemia, vitamin B2, B3 and vitamin C deficiency. ? Other rare systemic diseases. 4. pestle nail? Does this run in the family? Congenital heart disease. ? Iodine deficiency. 5. Is the nail surface sunken? Psoriasis and eczema. ? Ectopic dermatitis? Round and bald. 6. soft armor (soft and brittle nails)? Lack of vitamins A, B6, C and D? Hypocalcemia. ? Severe malnutrition. 7. nail bed separation? Iron deficiency anemia. ? Lack of vitamin B3. ? Bacterial infection. ? Trauma. ? Frequent contact with water. 8. V-shaped protrusions on baby nails are very common. Usually there is a bulge on the nail surface that converges to the center. At present, the cause is unknown, but it will improve itself when it grows up. 9. gray nails? Trauma (such as finger crushing). ? Rare genetic disease: white nails appear on every finger. 10. Straight white nails are different from the horizontal white lines mentioned above. The horizontal white line is caused by the stop of nail growth and has a slightly concave appearance, which is found on each finger. Linear white nails do not affect the nail surface, but the color turns white. The common causes are hypocalcemia and vitamin B3 deficiency. 1 1. Vertical onychomycosis is a nail problem related to skin color and race, which is the most common among blacks. About 2.5% of blacks aged 0 ~ 3 years have onychomycosis, and nearly 96% of blacks over 50 years old have onychomycosis. The incidence rate increases with age. Besides melanin activity, it is also related to the deficiency of vitamin B 12 and vitamin d 12. Small nail edge desquamation, nail edge desquamation and even tingling are usually caused by excessive dryness, repeated dry-wet cycle, abnormal metabolism of stratum corneum or trauma. It is common for children who have the habit of biting their nails and women who often do housework. Severe desquamation may have immune diseases (such as dermatomyositis). If you find small peeling or tingling, remember not to pull or break it at will to avoid bleeding or even paronychia caused by infection. It is suggested to use nail clippers or small scissors to remove the free end of barbs, and strengthen hand protection actions (such as rubbing lotion to moisturize). Non-staple food should be added in time to avoid iron deficiency anemia. Although breast milk is rich in nutrients, as the baby grows up, it still needs to ingest other foods to obtain various nutrients. If the breast-fed baby has not eaten non-staple food for more than 6 months, it is easy to have symptoms of iron deficiency anemia. Usually, the nail bed of infants is pink, and the nail bed of infants with iron deficiency anemia will be pale, and spoon-shaped nails will appear more seriously. Babies' nails should be trimmed regularly. Babies occasionally bite their fingers or put their hands in their mouths, making it easy to eat germs. Therefore, it is very important to keep your nails clean. It is suggested that the nursing staff can wipe the nail end with gauze towel to wipe off the dirt when bathing the baby. If you find stolen goods that are difficult to take out, don't try to dig with a hard needle. This will not only make them unable to clean, but also easily lead to nail bed peeling, and more susceptible to infection by bacteria or mold. In addition, the baby's nails should be trimmed regularly. For the baby, you can choose the special nail clippers for the baby sold in the market or the small scissors with arc-shaped knife surface (the edge of the nail will become smoother) and protective sleeves on the side (it is best to have arc-shaped protective design at the end of the scissors), so as to prevent the baby from accidentally scratching himself or scratching things and causing nail breakage or even bleeding.
